Ours is crapping out just like yours. Picture goes out, "black and white squiggles" appear in the top left of the screen then TV input appears, then it either repeats or gives me my picture back. This happens with both the HDMI slots (tested all 3) and both Component slots. Seems like the bulb or a circuit board on the TV is faulty. What a piece of ****, never spending another dime on LG products. I did get it to come back by hitting the back of the TV with a good slap, but it gets really annoying.
All symptoms in your TV shows that you need to replace its Lamp as it has been consumed its life hours and TV requires new lamp. Lamp can be obtained from Sony Website. Price is $200, Hope this info will help you to enjoy your Sony TV in coming days.
I had the same exact problem.
I removed the bulb and cleaned it. There is a small screen at the top of the bulb and it was covered with dust. Once it was cleaned I replaced the bulb and it solved the problem.
Thanks to those who posted the solutions
